Classloading: CachingProvider.getDefaultClassloader

[cruftex]

Most implementations I analyzed, including the RI, use the following as default classloader:

public ClassLoader getDefaultClassLoader() {
   return getClass().getClassLoader();
}

Alternatives, I can think of, which are legal at the moment as well:

• Bootstrap classloader
• Thread.currentThread().getContextClassLoader()
• keyClass.getClassloader()

Possibly will an implementation pass the TCK tests which decides for the TCCL as default. We should be more strict here, so users know precisely when to set the custom class loader.

The basic goal is that implementations should behave consistent.

At the moment I think the best way is to make the RI default mandatory.

Is TCCL a good option for a default classloader? The spec currently says:

Obtains the default ClassLoader that will be used by the CachingProvider

This is hard to guarantee with TCCL - it depends on context (by its very definition)
